A unique flat-file database module, written in pure perl. True multi-level
hash/array support (unlike MLDBM, which is faked), hybrid OO / tie() interface,
cross-platform FTPable files, ACID transactions, and is quite fast. Can handle
millions of keys and unlimited levels without significant slow-down. Written
from the ground-up in pure perl -- this is NOT a wrapper around a C-based DBM.
Out-of-the-box compatibility with Unix, Mac OS X and Windows.
